[Restish](https://rest.sh/) is a CLI for interacting with [REST](https://apisyouwonthate.com/blog/rest-and-hypermedia-in-2019)-ish HTTP APIs with some nice features built-in — like always having the latest API resources, fields, and operations available when they go live on the API without needing to install or update anything.

Check out [how Restish compares to cURL & HTTPie](https://rest.sh/#/comparison).



See the [user guide](https://rest.sh/#/guide) for how to install Restish and get started.
